2D binned fit

Roofit and RooStats
1

Dear Expert,

I have two 1D histograms and want to do a 2D binned fit using RooDataHist.

I tried to do like below:
RooDataHist * dataxy = new RooDataHist("dataxy","dataxy", RooArgList(mD0, mD0pi), h1);

But this is taking only one histogram. How do I identify these two different variables for 2D fit as now this takes only one histogram?

Can you please suggest it or there is any different way to do it?

Regards
Chanchal

Hi, I hope this helps you, with the information on your histograms you can fill a TH2, and then you need to pass the TH2 histogram to the RooDataHist.
